Abstract:
A valve timing control apparatus for an internal combustion engine, includes a housing body, a vane rotor, a first plate, and a second plate. The housing body is formed integrally with a shoe at an inside periphery of the housing body, wherein the shoe projects inwardly in a radial direction of the housing body, and wherein the housing body is formed with a sealing recess at an axial end of the housing body. The vane rotor is rotatably mounted in the housing body, wherein the vane rotor includes a vane, wherein the vane and the shoe define advance and retard chambers adapted to supply and drainage of fluid. The first plate is fixedly inserted in the sealing recess of the housing body, the first plate sealing the axial end of the housing body. The second plate seals another axial end of the housing body.
